Friday spells crash doom
There are several articles in this collection which discuss the causes of road fatalities. This one uses the data from 48 fatalities in Tasmania, to claim that Friday is the most dangerous day. Given the small numbers involved and the fact that there were 9 fatalities on Saturdays and 8 on Sundays, one should be cautious in making a strong claim like in the headline. Students can check the percentages given and suggest other reasons why just over half of the fatalities occurred on Fridays to Sundays.
